Specification of Letters Patent.

Patented Nov. 2 1917.

Application filed December 4, 1916. Serial No. 134,844 a To all whom it may concern:

Be it known that I, VIN'roN E. SISSON, a citizen of the United States, residing at Chicago, in the county of Cook and State useful Improvements in Diaphragm-Plate Buffer-Springs for Railway-Car Vestibules of which the following is a specification.

My invention relates to a buffer spring adapted to be interposed between the diaphragm face plate of a railway car vestibuleand the end of the car, for the purpose of maintaining the plate in engagement with. the corresponding element of the vestibule of the adjacent car and returning the plate to its normal position parallel to the end of the car after 1t has been displaced-f0r example, when the train rounds a curve. A device of this type is described and claimed in a patent to Frank G. Fowler, #1,019,777, patented March 12th, 1912.

One of the objects of my invention is to provide means for attaching the spring to the face plate, which will obviate the necessity of perforating, and thereby weakening, the spring leaves, as must be done if the springs begbolted or riveted to the plate.-

Another object of the invention is to provide retaining devices for the extremities of the spring, adapted to be firmly secured to the end wall of the car and furnished with rubbing plates for the ends of the spring to bear against, arranged so that they can be readily removed when worn out.

It is customary to employ in this connectiona compound semi-elliptical spring, the center portlon of which is rigidly attached to the face plate, while the extremities have a sliding engagement with the ends of the car, and this is the arrangement which is herein shown' and described' It would be possible, though for reasons of convenience not desirable, to reverse the position of the spring' fastening the center portion to the car endsand engaging the extremities wlth the face plate. Changes in I be made without departure from the intent and purpose of my invention as defined in the appended claims.

The invention is illustrated in the accompanying drawings wherein Figure 1 is a fragmentary plan view of the ends of adjoining vestibule railway cars details of construction might fitted with the diaphragm face plate buffer springs and attachments of my invention.

Fig. 2 1s a sectional view on line 2-2 of Fig. 1. of Illinois, have invented certain new and Fig. 3 is a fragmentary sectional plan on an enlarged scale taken on line 33 of Fig. 2.

Fig-.- 4 is a view in perspective of one of the bracket members forming part of the means for retaining the extremities of the spring in sliding engagement with the end wall of the car.

Fig. 5 is a similar view of one of the removable rubbing plates forming a part of said retaining means, and

Fig. 6 is a similar View of a part of the means employed for rigidly securing the center portion of the spring to the face plate.

Like characters of reference designate like parts in the several figures of the drawings.

Referring to the drawings, the end wall of the car is shown at 10 and the diaphragm face plate at 11. 12 is the buffer spring consisting preferably of a compound elliptical leaf spring, the leaves of which are secured together by a band 13 which is shrunk and pressed upon them so as to hold the leaves against movement with respect to each other. Secured to the face plate 11, for example by rivets 14;, is a channel-shaped bracket member 15, forming a seat for the center portion of the spring. 16 is a retaining device adapted. to fit into the bracket member 15 outside of 'the spring and formed with vertical perforations 17 made to aline with corresponding perforations in the bracket member, whereby the retaining member may be held pressed against the spring by bolts 18. The retaining member is formed with shoulders or abutments 19 adapted to stand on either side of and close to the edges of the spring band 13. The engagement between the shoulders and the band prevents lengthwise movement of the spring through the bracket 15,.

Each end of the master leaf 20 of the spring is bent over as indicated at 21 and pair of outstanding webs-24-2i 'formed' with perforations 25 for a bolt 26 adapted to be engaged by the hook or bent over portion 21 of the spring. Between the bracket member and the end of the spring is interposed a rubbing plate 26 formed with outstanding flanges 27 which preferably diverge a trifle, as manufactured, so that they are compressed with spring pressure when the rubbing plate is forced into place in the bracket. The rubbing plate is also pref erably formed with backwardly pro ecting ribs 28 engaging the edges of the bracket member. The flanges 27 of the rubbing plate are formed with perforations 29 so that the rubbing late is held in position in the bracket memiier by the bolt 26 above mentioned. .The rubbin plate may, however, be readily remove when it is worn out without detaching the bracket from the end of the car. The mannerin which the members 16 and 26 are constructed and applied so as to interlock with the spring band 13 and the bracket 22, respectively, prevents unnecessary movement between the various parts of the spring holding devices and thereby prevents the knocking or rattle which would be present if the parts were loosely engaged.

I claim:

1. The combination with the end wall and diaphragm face plate of a vestibuled iailway car, of a spring arranged between the aforesaid structural elements of the car, secured to one of them and having'a sliding engagement with the other, and a retaining device providing said sliding enga ement, which is fixed to one of said car e ements and has a removable rubbing plate against which the spring bears.
